But the user would not always be "postgres". To be accurate, it is
the user which owns the files for the "cluster" (database instance)
and which runs the database service. If a machine contains
multiple clusters it is (IMO) best practice, for both security and
operational reasons, to use a separate OS user for each cluster.
